Legionella bacteria are found in natural and man-made systems and thrive at temperatures between 25C and 45C. Although easily killed by disinfectants, water systems especially in large buildings frequently have stagnant areas, e.g. tanks and "dead legs", where disinfectants introduced no longer have effect, so water systems where temperatures are inadequately controlled will harbour Legionella bacteria.
If the legionella bacteria were to remain uncontrolled it may create a risk of legionnaires' disease, which is a form of pneumonia, to building occupants who may be susceptible because of age, illness, immunosuppression, smoking, etc.
